TABLE'i ATTACHMENT FOR TELEPHONES.

SPECIFICATION forming part of Letters Patent No. 647,737, dated April 17, 1900.

Application iiled November 23, 1899. Serial No. 738,011. (No model.)

To all whom it nwty concern: v

Beit known that I, GLENN S. WILLIAMSON, a citizen of the United States, and a resident of New York city, in the county of New York and State of New York, have invented a certain new and useful Tablet Attachment for Telephones, of which the following is a specification.

This invention relates to tablet attachments for telephones, and has for its object the construction of an attachment of this sort in a manner such that it can be readily applied to the cover of the battery-box of any make of telephone.

To this end the invention consists of a tablet attachment having securing means therefor which are capable of adjustment both for the Width and thickness of the battery-box cover.

The invention furtherf consists in the constructiomformation, and combination of parts substantially as hereinafter fully described and claimed. Y

In the accompanying drawings, which form a part of this specification, Figure 1 represents a telephone with my improved tablet attachment secured thereon. Fig. 2 represents my attachment as viewed from the under side. Fig. 3 is a transverse section of the attachment, taken on the line 3 3 in Fig. 2. Fig. 4. is a perspective view of one of the clamps by which the attachment is secured in place.

This attachmentis intended for application to the battery-box of ordinary wall-telephones. These battery-boxes vary in width, and for that reason the securing devices of the attachment must be adjustable. The covers of these battery-boxes also vary in thickness, and for that reason the clamps by which the attachment is secured in place must have adjusting means to accommodate covers of different thicknesses.

In the drawings, 6 refers to the cover of the battery-box.

7 refers to the base-piece of the tablet attachment.

8 refers to the paper-support, which is secured across the top of the base-piece.

9 refers to a paper-clip for holding a pad of paper to the support, while 10 and 11 refer to the clamps by which the attachment is se cured in place.

The base-piece 7 has its edges beveled upwardly, as indicated. The clamps are preferably metallic bars having their ends fitted to the beveled edges of the base-piece. They may be thus fitted by recurving them, as shown. The clamps thus constructed may either or bot-h be adjusted longitudinally of the base-piece to any position thereon, the clam p 11 readily passing under the paper-support 8, as indicated in Fig. 3. To secure these clamps in place upon the base-piece, any suita able means may be provided, such as a setscrew 12. To secure the clamps to the cover of the battery-box, they are provided with arms orlugs 13, through which pass set-screws 14 into engagement with the under surface of the battery-box cover.

The telephone illustrated in Fig. 1 has a battery-box of the maximum width, and to se= cu re the tablet attachment thereto the clamp 10 is placed near the left-hand end of the base-piece and the clamp 11 is placed under the paper attachment near the right-hand end of the base-piece. In adapting the attachment to a narrower battery box the clamps 10 and 11 will be brought nearer together upon the base-piece and clamped in position such that their set-screws 14 will engage the under surface of the battery-box cover, as in the instance illustrated.

By mounting the paper-support on top of the base-piece room is left for the ends of the clamp l1 to slide along the beveled edges of the base-piece under the papersupport. Then, too, said support is by this manner of mounting lraised above the bead-16 usually found upon the cover 6. Still another useful function results from this arrangement when the attachment is applied to a Wide batterybox, as shown--namely, the lower end of the paper-support can rest upon said bead and make a lirmer rest for the arm of the person using the telephone or tablet.

The formation of the parts of my improved attachment may be changed and their arrangement varied Without departing from the invention.

I claim as my invention- 1. A tablet attachment for telephones, con- IOO sisting of a base-piece, a paper holder or sup-` port rigidly secured on top thereof and in a manner to leave vthe edges ofthe base-piece unobstructed-beneath the paper-support and clamps -tted to the edges of said base-piece and adjustable along the same independently a of and beneath the paper-,support whereby the attachment'may be readily fitted to various telephones.

2. In ay tablet attachment for telephones,

the combination with a base-piece having its edges beveled, of a' clamp having its ends'fit- Atedto said beveled edges in a manner to sef cure it to the base-piece and renderit adjust# able longitudinally thereof, and a set-screw for fixing said clamp in anyldesred position.y 3,. A clamp for a tablet attachment for telephones consistingof a bar having recurved ends for' engagement with the base-pieceol" the attachment, a screw passing through the.

bar forsecuri'ng it in rplacefandpan arm or lu-g projecting from the bar, and prosgided with a set-screw whereby to secure the attachment in place vupon a telephone.

4. A tablet attachment for telephones, consisting of lthe base-piece provided with the upwardly-beveled edges, the paper support or holder secured on top thereof, and clamps secured to the beveled edges of thel base-piece, and each adjustable longitudinally thereof throughout the llength of the base piece, whereby the attachment may be fitted tovarioustelephones. n e
